Abstract

A scheme of a random access Msg3 transmitted on a first eNB and common UL information distribution transmission power transmitted on a second eNB in a DC system is provided. The Msg3 and the common UL information are simultaneously transmitted or a time difference is not considered. The scheme comprises the following steps of distributing first transmission power which equals to actual power needed by a physical channel for the physical channel which possesses the highest priority content and transmitting the Msg3 and the common UL information based on a priority sequence if total transmission power actually needed by UE is greater than configured largest transmission power; based on difference value power of the largest transmission power configured by the UE and first transmission power, distributing power for a physical channel transmitting a secondary priority content, wherein if the difference value power is less than transmission power actually needed by the physical channel transmitting the secondary priority content, the power is distributed for the physical channel transmitting the secondary priority content based on the difference value power; otherwise, the power actually needed by the physical channel transmitting the secondary priority content is directly distributed for the physical channel.

Description

For the message 3 transmitted in dual link and common UL information distribution power simultaneously

Technical field

The present invention relates to dual link communication system, particularly relate to the method and apparatus of generic uplink information distribution through-put power for the message 3 of Stochastic accessing that the PUSCH of the first base station that transmits transmits and the PUCCH/PUSCH of the second base station are transmitted simultaneously in dual link communication system.

Background technology

In LET-A version 12, dual link (Dual Connectivity:DC) is a kind of running status, user equipment (UE) given under this running status uses the Radio Resource provided by two different network nodes, these two different network nodes are such as macro base station MeNB and small-cell base station SeNB, are connected in an rrc-connected mode between them with nonideal backhaul network.Macro base station MeNB ends at least one S1-MME (Mobility Management Entity) and the mobile anchor point be therefore embodied as towards core net.Small-cell base station SeNB provides additional Radio Resource for this subscriber equipment.

Owing to having independently scheduler and backhaul network link is not desirable on macro base station MeNB and small-cell base station SeNB respectively, that is its time delay is not zero, so these two base stations and macro base station MeNB and small-cell base station SeNB attempt improving the through-put power of subscriber equipment and are possible and cause this subscriber equipment to exceed its maximum transmit power capabilities PCMAX (i.e. power contest thus simultaneously, see " Physicallayer aspectsfor dual connectivity ", Qualcomm, 3GPP RAN1#76).This problem can be alleviated in the larger scope of carrier aggregation, because scheduling decision can being coordinated in this base stations all inter-cell unitedly.

At following three sections of documents, i.e. " UL power control for dual connectivity ", Samsung, 3GPP RAN1#76, " Physical layer enhancement for dualconnectivity ", Hitachi, 3GPP RAN1#76 and " Views on open issues fordual connectivity ", NTT DoCoMo, distribute in 3GPP RAN1#76 and define novel power adjustment and the possible solution of priority rule, method of adjustment uneven in first section of document is applied to the PUSCH transmission with different carryings and different data contents on macro base station MeNB and small-cell base station SeNB.The novel power adjustment for the transmission simultaneously of the PUCCH on macro base station MeNB and small-cell base station SeNB and priority rule is defined in second section of document.The adjustment of a kind of novel power and priority mechanism is proposed, for the PRACH transmission carried out simultaneously, because content-based Stochastic accessing (RA) is used to small-cell base station SeNB in the 3rd section of document.

But above document is not all provided for power adjustment and the priority mechanism of the UL transmission of the transmission of message 3 (Msg3) of the RA appeared on the PUSCH of a base station and common on PUCCH and/or PUSCH of another base station simultaneously.Note, in carrier aggregation in current lte-a system, content-based RA only implements on PCell and non-competing RA implements on SCell, and namely the UL transmission of the transmission of the Msg3 of RA and common on PUCCH/PUSCH can not occur in carrier aggregation simultaneously.

Summary of the invention

Propose the adjustment of a kind of novel power and priority mechanism in the present invention, common UL on transmission for the Msg3 of the RA on the PUSCH of a base station and the PUCCH/PUSCH in another base station transmits the situation simultaneously occurred, and then guarantees the maximum transmission power that can not exceed subscriber equipment.
